\maketitle
Use \cmd{\nolbreaks}\marg{some text} to prevent line-breaks in
\meta{some text}. This has the advantage over \verb+\mbox{ }+ that
glue (rubber space) remains flexible, and can adjust to fit the margins.
It has the disadvantage of not working in all cases! Most common
situations are handled (in particular, \cmd{\newline}, \cmd{\linebreak},
and \cmd{\\} are disabled) but spaces hidden in macros or \verb+{ }+
(braces) can still create break-points.
Large pieces of text with no breaks can cause problems with
paragraph justification. Using the alternate \cmd{\nolbreaks}\verb'*'
allows a line before the unbreakable text to be cut short
(like ragged-right). Giving the package option \opt{[ragged]}
converts all \cmd{\nolbreaks} commands to \cmd{\nolbreaks*}.
You should declare \cmd{\sloppy} or set a raised \cmd{\tolerance} in
your document when you have large non-breaking chunks.
The command name \cmd{\nolbreaks} is long to type, so you should
probably declare a shorter alias name if you use it a lot, like
\ \verb'\newcommand\n{\nolbreaks}'.
